What would you do on the last day of earth? Griffin and Sabrina just wanted to run a marathon by themselves on the last day of earth but their unique choice inspired 100,000 others to join them for a full blown, organized last race in Austin, TX. The end of the human race creates a duality of civilized beauty versus maniacal death and destruction. Successful Psychiatrist, Dr. Jimmy Spangle, watches Griffin's inspiration with violent rage to recruit his army to hunt down and kill them before they finish. Austin's chief of police, Tank Miller, pauses his troops last day celebration party to defend Griffin and his friends for the death match of a lifetime while the entire world watches the race's battle unfold through the manipulation duel of a sociopathic TV anchor and her on-site host.
